Not too bright, fellow! JJ declined to participate in the scrimmage portion of the pre-draft camp, and wanted only to go to the testing portion. That is only reserved for the elite of the draft and you have to be invited. They did not invite him.
At least he has not hired an agent yet. He needs to go back to school. I'm sure that he'd still get a private workout with a few teams, but I have to believe his stock will drop considerably right now. If he stays in the Draft, he will likely get drafted in the 2nd round, but I see him heading to the D-League this season. I fear that he may be heading to that sad place where kids get bad advice, come out but dont get far in the NBA and end up playing in Europe somewhere.
Go back to school. Learn the game better and hone your skills. Come out next yr.
